Definitions

  • the invention relates to a floor panel with one on at least one side edge (Connecting edge) formed spring and one on the opposite side edge (Connecting edge) formed by an upper projection and one side groove limited beyond the upper protrusion, the tongue and the groove being provided with corresponding locking means are, so that two identical panels in both the horizontal and vertical directions can be locked together, and wherein the tongue and the groove with the associated Locking means are designed so that two panels by both horizontal Moving towards each other as well as by angled insertion of the spring are interconnectable in the groove.
  • Such a panel is known for example from US-A-6,006,486.
  • a majority Such floor panels can be connected to each other without them on the Glued underground or with each other by additional connecting links such.
  • B. Rails must be connected.
  • the connecting edges of two floor panels can, for example, by pushing straight into each other parallel to the ground be joined together, in this case to achieve a positive fit between the connecting edges, the lower projection of the first connecting edge must be bent down during the assembly and then he due to its elastic effect back to its original position snaps back and reaches behind the upper projection on the underside of the spring, so that the two connecting edges are not simply pulled apart in a straight line can be separated.
  • Such panels are generally called Referred to as click profiles.
  • a disadvantage of the known panels is that when they are installed, they are already installed Panel must be raised significantly when a new panel is added should. Since panels that have already been laid are usually connected to other panels, they are difficult to lift off the ground. If the load is too high lower projection and / or the spring can damage a connecting edge become.
  • Interconnected panels must be close together so that none Gap formation in the floor occurs, which can be problematic and tends to a high tension of the two connecting edges of two panels in the lower area between the lower projection of the first connecting edge and the spring of the second connecting edge.
  • connection edges are particularly complex in the case of complex shaping inside the groove, usually extremely difficult to manufacture.
  • routing of the milling cutters required to form the connecting edges is complex, resulting in higher wear in the areas of elaborate guidance can lead.
  • a generic floor panel is characterized by that the locking means belonging to the groove is completely in the region of the lower projection is arranged, which projects laterally beyond the upper projection.
  • the latching means are further preferably formed on the underside of the spring Additional ridges and additional recesses formed on the top of the lower projection educated. In this way the tongue of a panel can be angled slightly be inserted into the groove of another panel. Are the two panels on one level, the locking means cause the panels to drift apart prevented.
  • the top and bottom of the spring face each other inclined surfaces on and the top of the lower projection and the bottom of the upper projection also have flat, inclined surfaces.
  • the upper side of the spring and the lower side of the upper projection are preferably located as well as the underside of the spring and the top of the lower projection when mating the connecting edges to each other. This creates a stable connection ensures a good seal between the system edges on the Top sides as well as a stable and very tight connection through the two connection profiles is reached in the lower area.
  • the first connecting edge and the second connecting edge is designed in such a way that it does not deform temporarily are mergable.
  • first connecting edge and a second connecting edge When joining a first connecting edge and a second connecting edge is advantageously an upper space between the contact edges and the spring as well as a lower free space between a front, the tongue and a groove base the recess formed.
  • the free space enables the Contact edges. Any contamination of the panels, such as. B. by dust, are in Free space is deposited and therefore do not interfere with the connection of the system edges.
  • the lower projection When joining a first connecting edge and a second connecting edge between a lower edge of the second connection edge and a lower edge the lower projection preferably remains a distance. This allows to ensure that the contact edges of the panels are the most exposed parts of the connection and thereby complete flush.
  • the upper increase and the upper additional increase the spring in the lower recess and the lower additional recess of the lower one Projection as well as the lower additional increase in the upper additional recess of the The spring can advantageously be positively received.
  • the first connecting edge is on upper projection advantageously a sliding point to rest on the top of the spring an adjacent second connecting edge is formed.
  • the two floor panels can with a relatively low tension or even with no tension at all, which increases the risk of material fatigue reduced.
  • the upper increase of the spring, the upper additional increase of the spring, the lower increase of the lower projection and the lower additional increase of the rounded lower projection preferably extends below or at a level with an extension of the top of the lower tab. Since the increases and additional increases are made relatively small is a deliberate separation of the two connecting edges in the opposite direction possible without too much leverage for the spring, so that a break of the lower projection and / or the spring can be prevented.
  • the floor panel preferably has connecting edges on the long side thereof Increases and additional increases form-fitting from another connecting edge another floor panel can be picked up and the transverse edges have connecting edges with rounded increases and rounded additional increases.
  • the connection is particularly suitable for the longitudinal edge of floor panels, because here the two panels can be brought together and then in the longitudinal direction the floor panels can be continued until the transverse edge of the floor panel engages with another transverse edge of another floor panel comes.
  • connection points can be exerted on these four connection surfaces be distributed so that the increases and additional increases themselves relative can be made small and still pull apart laterally Panels well prevented.
  • the connecting edges can also lie in one another so that there are only four connecting points form. This does not make the sealing as good as four Connection surfaces reached, but it is a horizontal pushing together without an arc Movement of two panels possible.
  • a connection panel 1 has a first connection edge 10 and on the opposite side a second connection edge 11.
  • the two connecting edges are designed such that they are suitable for mutual engagement with one another, as shown in FIGS. 1 and 2 .
  • the first connecting edge 10 of the floor panel 1 has an upper projection 6, a lower projection 5 and a groove 3 arranged between the two projections.
  • a contact edge 8 is formed at the upper end of the upper projection 6.
  • the groove 3 has a groove base 29 and is delimited by the upper side 13 of the lower projection 5 and the lower side 22 of the upper projection 6, the lower side 22 of the upper projection 6 and the upper side 13 of the lower projection 5 being inclined toward the groove base 29 , so that the groove 3 tapers towards the groove base 29.
  • a connecting profile is formed, which has a lower elevation 27 and a lower recess 28 formed next to it in the direction of the groove base 29.
  • a lower additional elevation 17 and a lower additional depression 18 formed adjacent to the groove base 29 are provided. Both the lower elevation and the lower additional elevation 17 lie essentially on the line of the extension of the upper side 13 of the lower projection 5, but they can also protrude somewhat beyond.
  • the floor panel 2 has a spring 4 on its second connecting edge 11, which is suitable for insertion or engagement in the groove 3. Protrudes above the spring 4 Connection web 7 protrudes outwards, on the outside of which a second contact edge 9 is formed, the connection of the two connecting edges on the first Contact edge 8 of the first floor panel 1 abuts.
  • the spring 4 has at least in Substantially flat, preferably completely flat top 23 and bottom 12, the run towards each other inclined towards the spring front side 30, so that the spring 4 is tapered.
  • At the bottom of the spring 4 is a second connection profile formed having an upper recess 26 which is the lower end of the Defined spring 4, and an upper elevation formed next to the upper recess 26 25. According to the invention there are also an upper additional increase 15 next to the upper one Increase 25 and between the upper increase 25 and the upper additional increase 15 an upper additional recess 16 is formed.
  • the two connecting edges 10 and 11 of the floor panels 1 and 2 are inserted into one another according to the arrow P1 of FIG. 1 by an arc-shaped relative movement.
  • the floor panel 1 with the first connecting edge 10 already lies on the substrate, so that the second floor panel 2 with the second connecting edge 11 can be used according to the arrow P1 due to the arcuate movement.
  • the tongue 4 is inserted into the groove 3, the upper side 23 of the tongue 4 being able to slide along a first sliding point 19 of the upper projection 6 and a lower sliding point 14 being able to slide along the underside of the tongue on the upper side 13 of the lower projection 5.
  • the contact edges 8, 9 can lie against one another, so that there is an essentially circular insertion movement until the two connecting edges 10, 11 are inserted into one another according to FIG. 2.
  • the upper sides 35, 36 and the lower sides 37, 38 of the floor panels 1, 2 form straight lines, the upper sides 35, 36 in particular forming an uninterrupted line.
  • the two floor panels 1, 2 are in particular at their contact edges 8, 9 in the upper area and in the lower area in the two connecting profiles.
  • An upper free space 21 is formed between the contact edges and the contact point formed by the sliding point 19 and the spring upper side 23, and a lower free space 20 between the groove base 29 and the spring front side 30.
  • particles such as dust etc . which rested on the connecting edges before joining, are pressed without the connection between the two floor panels 1, 2 being thereby disturbed.
  • a distance 31 is formed on the undersides 37, 38 between a substantially vertically running lower edge 32 of the second connecting edge 11 and a likewise substantially vertically running lower edge 33 on the lower projection 5 of the first connecting edge 10, so that the contact in the lower region is guaranteed by the two connection profiles.
  • the lower elevation 27 of the lower projection 5 lies in the upper recess 26, the lower additional elevation 17 in the upper additional depression 16, the upper elevation 25 in the lower depression 28 and the upper additional elevation 15 in the lower additional elevation 18.
  • the upper additional elevation 15 rests with a flank on a lower additional contact surface 34 of the lower projection 5.
  • connection shown in FIGS. 1 and 2 is particularly suitable for the longitudinal edge of floor panels 1, 2, since here the two panels can be guided into one another according to the arrow movement P1 and can then be continued in the longitudinal direction of the floor panels until the transverse edge of the floor panels 2 another transverse edge of another floor panel comes to rest.
  • the first connecting edge 110 of the first floor panels 1 accordingly has an upper projection 6, a lower projection 105 and a groove 3 formed thereby.
  • the connecting profile of the first connecting edge 110 has a lower elevation 127, a lower depression 128 arranged next to the groove base, a lower additional elevation 117 arranged next to it, and a lower additional depression 118 arranged next to it, which in turn delimits the groove base 29 by a lower additional contact surface 134 is.
  • the second connecting edge 111 has a spring 104, on the underside of which an upper recess 126 defines the lower end of the spring 104.
  • an upper elevation 125, an upper additional depression 116 arranged next to it and an upper additional elevation 115 are formed, the upper additional depression 116 being formed between the upper elevation 125 and the upper additional elevation 115.
  • the height of the depressions and additional depressions in FIGS. 1, 2 can correspond, for example, to one to two twentieths of the total height of the floor panel, in FIGS. 3 , 4 it can correspond, for example, to one to three, preferably one to two thirtieths of the total height of the floor panel.
  • the two floor panels 1, 2 can be joined into each other according to the arrows P2 and P3 by a linear relative movement, the upper elevation 125, the upper additional elevation 115, the lower elevation 127 and the lower additional elevation 117 sliding together, which is facilitated by the rounding.
  • the lower projection 105 or the spring 104 does not have to be bent away when joining one another, but it is also possible to insert one into the other with a slight bend, in particular of the lower projection 105.
  • the two edges lie one inside the other in such a way that connection points 40, 41, 42 and 43 are formed between the connection edges 110, 111. Although this does not result in a seal that is quite as good as that provided by the four connecting surfaces in FIG. 2 , it is possible to slide one into the other without an arcuate movement and nevertheless a good seal is possible using the four contact points.
  • the connecting edges 10, 11, 110, 111 according to the invention can easily be produced according to FIG. 5 by corresponding milling machines or other tools 40, 41, 42, 43 being moved in a straight line along the arrow directions directly onto the edges, without having to form complicated, engaging structures and the milling machines z. B. must be performed in an arc. In particular, this also benefits the milling heads 50, 51, 52, 53, which therefore experience less wear.
